MapGuide Open Source 2.4 Released

The project that initially emerged from Autodesk and became MapGuide Open Source just released its version 2.4.

I haven't found a summary of the changes so far. There seems to be numerous improvements to MapGuide OS's core, to Fusion Tools and FDO. Here's what looks like their list of major new items:

  • A new service for profiling performance (RFC 110)
  • Web Tier directories now include SVN metadata, allowing for the pulling of viewer updates and fixes instantly with a subversion client (RFC 111)
  • Path scaling support in Symbol Definitions (RFC 113)
  • New Feature Service API for save points RFC 114
  • Improved Coordinate System conversion performance (RFC 116)
  • IPv6 support (RFC 118)
  • Support for enhanced URL information in Layer Definitions (RFC 119)
  • Configurable Coordinate System dictonary paths via serverconfig.ini and webconfig.ini (RFC 122)
  • Feature Join performance optimizations (RFC 123 and  
  • Toggle-able tooltips for AJAX and Fusion viewers (RFC 120)
  • Lots of performance and usability improvements in Fusion (see  this link for an overview)
  • Datum Transformation enhancements (RFC 94)
  • WMS 1.3.0 support (RFC 95)
  • QuickPlot? command for AJAX and Fusion viewers (RFC 96)
  • EPSG/SRID code changes (RFC 98)
  • WFS 1.1.0 support (RFC 106)
  • Watermark support (RFC 108)

My main question when MapGuide Open Source comes to my mind: what's the status of its adoption? I had a lot of hopes for it when Autodesk made MapGuide open source along with providing the financial support for OSGeo's birth, but it seems like MapGuide does not get much love nowadays, at least not as much as competing solutions like GeoServer and MapServer. Any comments?

OpenGeo Suite 3.0 is Out!

Newest version of the OpenGeo Suite has just been released and it comes with the following goodies.

  • Server-side processing
    • OGC Web Processing Service (WPS) provides a standard for inputs and outputs (requests and responses) for geospatial processing services such as polygon overlays, buffers, or custom processes.
    • Rendering transformations make processing operations easier in browser-based visualizations by enabling just-in-time use of any WPS process as part of any layer’s style.
    • Server-side scripting in Python and JavaScript allows users to easily deploy their own server-side processes using concise and straightforward APIs.
    • PostGIS 2.0 brings vector and raster analysis into the database.
  • GeoServer security now supports user groups as well as a number of new authentication mechanisms including LDAP, digest and X.509 certificate authentication.
  • Virtual services allow GeoServer to support multi-tenancy, enabling a single GeoServer instance to publish multiple service endpoints.
  • A new caching configuration interface in GeoServer includes the ability to define new grid sets, specify which layers to cache, seed or truncate the cache, and more.
  • OGC Web Feature Service 2.0 (WFS) adds some interesting new capabilities, including paging, stored queries, and extended operators.
  • Upgraded components, including the adoption of GeoServer 2.2, PostGIS 2.0, and GeoWebCache 1.3

Rasdaman: Geospatial Raster Data Manager

I had to investigate OGC's WCS standard and in the process I learned about Rasdaman, a geospatial radar data manager software which is apparently the only software that currently support WCS 2.0 both as a server and client. Rasdaman exists both in a commercial 'rasdaman enterprise' version and as open source with the 'rasdaman community' version. We never really mentioned rasdaman before.

The rasdaman community introduction: "Rasdaman extends standard relational database systems with the ability to store and retrieve multi-dimensional raster data ( arrays) of unlimited size through an  SQL-style query language. On such sensor, image, or statistics data appearing, e.g., in earth, space, and life science applications rasdaman allows to quickly set up array-intensive services which are distinguished by their flexibility, speed, and scalability.

Rasdaman is brought to you by the guys writing the geo raster standards, including  OGC WCS and  WCPS, the OGC raster query language. The petascope component of rasdaman provides service interfaces based on the  OGC  WCS,  WCPS,  WCS-T, and  WPS. For several of these, rasdaman will be reference implementation. Since April, rasdaman is available on the  OSGeo Live DVD. Rasdaman embeds itself smoothly into  PostgreSQL; further, a  GDAL rasdaman driver is available, and likewise a  MapServer integration (beta). A  PostGIS query language integration is under work, see our planning. EarthLook is a demonstration site showcasing rasdaman in a variety of 1-D to 4-D geo use cases."

New ‘Geoscience Data Journal’

A colleague informed me of the new Open Access 'Geoscience Data Journal', specifically for describing geospatial datasets.

From their aims and scope: "Geoscience Data Journal provides an Open Access platform where scientific data can be formally published, in a way that includes scientific peer-review. Thus the dataset creator attains full credit for their efforts, while also improving the scientific record, providing version control for the community and allowing major datasets to be fully described, cited and discovered. An online-only journal, GDJ publishes short data papers cross-linked to – and citing – datasets that have been deposited in approved data centres and awarded DOIs."

Their content description: "A data article describes a dataset, giving details of its collection, processing, file formats etc., but does not go into detail of any scientific analysis of the dataset or draw conclusions from that data. The data paper should allow the reader to understand the when, why and how the data was collected, and what the data is."

OpenGeoDa: An Introduction to Spatial Data Analysis

Via the OGD blog I learned about OpenGeoDa, an open source software program that serves as an introduction to spatial data analysis. The initial (closed) version was released in and they claim about 70,000 users. While we mentioned GeoDa before, it's really the first time we share about its existence with our users.

Here's what it is: "It is designed to implement techniques for exploratory spatial data analysis (ESDA) on lattice data (points and polygons). The free program provides a user friendly and graphical interface to methods of descriptive spatial data analysis, such as spatial autocorrelation statistics, as well as basic spatial regression functionality. The latest version contains several new features such as a cartogram, a refined map movie, parallel coordinate plot, 3D visualization, conditional plots (and maps) and spatial regression."
